Jef Pauwels

I study the operational structure of quantum correlations and communication, with a particular focus on resource-constrained quantum communication, device-independent and semi-device-independent certification, and the structure of entangled quantum measurements.

More broadly, I am interested in understanding which correlations are physically possible, which resources are required to generate them, and how these structures can be exploited to certify quantum systems.

I am currently a postdoctoral researcher at Université de Genève in the group of Nicolas Gisin. I completed my PhD at Université libre de Bruxelles under the supervision of Stefano Pironio.

This site gives a short overview of my publications, selected talks, and CV.

Highlights

• August 2026: New preprint: The Entanglement Content of Quantum Measurement Bases. With Otfried Gühne we showed that not all forms of entanglement can appear in an iso-entangled basis.
• July 2026: New preprint: Bipartite Bound Information Exists, where we solve the 25-year-old bound information conjecture.
• June 2026: New preprint: Certification of the genuine resolution of photon number resolving detectors, where we apply ideas from semi-device-independent certification to photon-number-resolving detectors. I used Codex to turn Python code into an interactive web application.
• March 2026: New review article: Quantum correlations in prepare-and-measure scenarios and their semi-device-independent applications. Comments very welcome.
• January 2026: Contributed talk at QIP 2026 on symmetric localizable multipartite quantum measurements. Slides.
• August 2025: Invited talk at QCrypt 2025 on routed Bell tests and DIQKD. Recorded talk.
• April 14, 2025: My work on classifying joint quantum measurements was featured in APS Physics Viewpoint, Entanglement as the Currency of Quantum Measurement.
